The CHC X90 is the GNSS survey solution selected by large number
of surveyors for its outstanding performances and reliability. Its is a
powerful and cost effective GNSS receiver designed for every day
field works.

RTK Performances

The X90 offers greater performances with GNSS functionality. The
GPS+GLONASS feature increases availability in obstructed sky
conditions such as construction sites in urban areas while securing
RTK accuracy and fast initialization. Its optimized power
management allows half day of non-stop RTK work with a single
battery.

Cable Free

Built-in GNSS engine, antenna, Bluetooth® communication and
optional UHF and GSM/GPRS modules in one single unit. The X90
base station can integrate a 1W internal UHF transmitter for an easy
deployment in most construction sites.

Compact and lightweight

The size of 20cm×8.5cm makes the X90 only weight 1,4 kg. It
significantly reduces tiredness of the surveyors in the field work.

Competitive and Reliable

The X90 GNSS is the first-choice solution for GPS+GLONASS RTK
surveying at fraction of cost.
